Hi German,
You're right - when the Accessibility toolkit (MDL-69863) was added, tool_brickfield and block_accessreview were listed as additional plugins. They are now standard plugins, however you may want to wait a day or two for Moodle 3.11rc 1 to be released before translating them, as some of the strings are due to be changed. Also, a few strings were included by mistake, as they are unused and have to be removed (MDL-71584).
